- System
- Fuel accumulators are mainly used on Bosch CIS (K-Jetronic and KE-Jetronic) on older Mercedes, VW, Audi, Volvo, Porsche and Saab models. They hold residual fuel pressure for hot starts, so confirm your car has one.
- Bosch number match
- Match the Bosch or OE number and the banjo fitting sizes. Accumulators differ in volume and fittings between applications.
- New sealing washers
- Fit new copper or aluminum crush washers on every banjo joint. High-pressure fuel leaks are a fire risk.
Brands that matter
- Bosch: Original manufacturer of CIS accumulators.
What to avoid
- Reusing old crush washers
- Replacing the accumulator before checking residual pressure with a gauge
Questions
What symptom points to the accumulator?
